Looking for my 71 Demon 340

I've been trying to use the web search services but most don't like the shorter VIN's of the older cars. I'm looking for my 71 Demon 340, vin LM29H1B382210. It was black on black, 4 speed, posi w 3.91s, tach, tuff steering wheel and AM radio. As far as I know it was last registered in western New York. Any leads would be greatly appreciated.
